Background technique

In order to meet different usage needs and application fields, modular design has gradually become the mainstream trend of electronic devices. Existing modular electronic devices usually include organic casings and removable modules installed on the casings, among which removable hard disks are the most common , The removable module is usually provided with a handle for the user to grab. When the user wants to replace the removable hard disk, he can apply force to the handle to overcome the relative electrical connection between the electrical connector of the removable module and the connected circuit board. The combined plugging force of the connectors drives the removable module out of the casing. However, when the combined plugging force between the two electrical connectors is too large, the user often cannot easily withdraw the removable module. In addition, although some modular electronic devices are equipped with an ejection mechanism for ejecting the removable module, the structure is relatively complicated and affects the appearance and internal space configuration, which is not conducive to the overall appearance design and the miniaturization and thinning of the electronic device. , so there is still a need for improvement.
